Most cases of plantar fasciitis resolve with time and conservative
methods of treatment. Usually for the first few weeks, people are
advised to rest, orthotics, possibly
physiotherapy. If these measures do not work, extracorporeal shockwave
The cause of plantar fasciitis is thought to likely have several contributing factors. The plantar fascia is a thick fibrous band of connective tissue that originates from the medial tubercle and anterior aspect of the heel bone. From there, the fascia extends along the sole of the foot before inserting at the base of the toes, and supports the arch of the foot.
Plantar fasciitis is due to a noninflammatory structural breakdown of
the plantar fascia. The structural breakdown of the plantar fascia is
believed to be the result of repetitive microtrauma. Microscopic
examination of the plantar fascia often shows myxomatous degeneration,
connective tissue calcium deposits, and disorganized collagen fibers.
Disruptions in the plantar fascia's normal mechanical movement during standing and walking contribute to the development of plantar fasciitis by placing excess strain on the calcaneal tuberosity. Other studies have also suggested that plantar fasciitis is not actually due to inflamed plantar fascia, but may be a tendon injury involving the flexor digitorum brevis muscle located immediately deep to the plantar fascia.
